The Sydney-born actress, 32 years Penn's junior, is the product of Vincent D'Onofrio's marriage to Italian Australian actress Greta Scacchi. Mother and daughter have performed alongside each other onstage, appearing together in a 2014 Perth production of Anton Chekhov's The Seagull.

The relationship follows Penn's much-publicised partnership with fellow actor Charlize Theron, with the pair announcing their engagement in December 2014 before splitting six months later.

Penn was previously married to actor Robin Wright from 1996 to 2010, and to pop icon Madonna from 1985 to 1989.

Reports surfaced in the media that Theron had simply refused to return his calls one day and started 'ghosting him'.

"And the f***ing ghosting thing, like literally, I still don't even know what it is. It's just its own beast. We were in a relationship and then it didn't work anymore. And we both decided to separate. That's it," she said.
